LATERAL-MOTION APPLIANCE FOR LOCOMOTIVE DRIVING-BOXES.

' Driving-Boxes, of which improvement the following is a specification.

My invention relates to means for afi'ording and controlling lateral motion in the drivingboxes of locomotive engines, and its object is to provide an appliance of such type which shall be of simple construction and ready applicability in locomotives ofthe various present standard types, with the operative result of enabling a locomotive having a comparatively long rigid wheel base to pass through curves of comparatively short radius, without liability to derailment, and without inducing undue or excessive wear of wheel flanges and rails.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 isa plan or top view, partly insectlon on the line a a of Fig. 2, of a portion of a locomotive frame and a pair of driving boxes,

illustrating an application of my invention; Flg. 2, a vertical transverse section through the frame members, taken partly on the line b b and partly on the line a a of Fig. 1;

Each of the side frame members comprises, so far as the portion thereof m which the driving axles'are fitted is concerned, the

usual top rail, 1, bottom rail, 2, and connecting vertical pedestal, each of which consists Specification of Letters Patent. P t ted M 23, 191

of a pair of pedestal jaws, 3, in which a drivng box, 4:, is fitted between a wedge, 4 anda shoe, 4*, in the ordinary manner. The open spaces between the sections of' the lower frame rail at the bottoms of the pedestals are spanned by pedestal ties, 5, suitably connected to the bottom frame rail. Referring first to Figs. 1 to 3 inclusive,

in the practice of my invention, the driving boxes, 4, of the leading driving axle, 8, are

of substantiallythe ordinary construction, exceptin the particular that they afford a materially greater space for lateral motion between t'heir'end flanges, 4 and the ped estal wedges, 4 and shoes, 4P, than in usual practice. Ordinarily, about one thirty sec- 0nd of an inch of lateral motion, on each side, is provided, but in this instance, the space-between the end flanges of the driving boxes has been made such that the lateral motion of'the driving boxes shall be about one inch on each side.

The opposite side frame members are connected, on each side of the driving axle, 8, by one of a pair of cross ties or spacers, 7, having flanges on their. ends which are secured to the pedestal jaws, 3, by bolts, 7*.

A cylindrical spring case, 7*, is formed on each of the cross ties, and a helical spring, 9, is fitted ineach of the spring cases. Inner and outer spring coils, of different tension, may, as shown in the drawings, be applied in the spring cases, instead of 1 single springs. The springs, 9, abut at their ends, on plun ers, 10, which are fitted to slide longitudinally. in the ends portions of the spring cases, which'are ored out to admit of their movement there n without undue friction. The outward movements of the plungers, effected by the tension of the springs, 9, ,are limited by" transverse stop pins, 10*,1fitted in the spring cases, said stop pins also providing abutments for. the-- springs when pressed in the opposite direc tion. A shoe, 11, having a spherical face fitting a corresponding recess in the outer ;endof'the plunger, is fiexiblyconnected to each of the plungers by a horizontal bolt, 10, the opposite facesof the shoes abutting on the inner flanges, 4 of the driving boxes.

The distance between the outer or working faces of the shoes, 11, is made exactlyv equal to the distance between the inner. flanges of the'driving-boxes, when the latter are in their central positions relatively to the frame members, and the ordinary degree of lateral motion is provided between the boxes, when in central position. The

- usual practice in locomotive building, for

.-motion takes place. .The wear of the rails will be correspondingly reduced, and the traverse of the locomotive through curves.

. connecting said members, driving boxes standard gage, is to allow one eighth of an inch on each side between the wheel hubs and the outer faces of the driving boxes, and this practice may be followedunder my invention. v

The structural modification illustrated in Figs. 4 to 6 inclusive, accords, in all substantial particulars, with the construction above described, and diflers therefrom inthat the shoes, 11-, are dispensed with, and the plungers bear directly on the inner faces of the driving boxes.

It will be obvious that, if desired, the driving boxes of the rear driving axle may be adapted for lateral motion, in the same manner as those of the leading driving axle.

In the operation of a locomotive engine in which my invention is applied, when the locomotive enters a curve, if suflicient pres sure is exerted against the flange of the driving wheel on the outer side of the curve by the. contact thereof with the outer rail, the outer driving box will be deflected from its central position, thereby compressing the springs, and the wear of the flanges of the leading pair of driving wheels will be reduced, inasmuch as the pressure can not become excessive before deflection or lateral be facilitated. A further advantage of my invention is attained inthe ability-to apply it in locomotives ofthe ordinary construc-' tion and with driving boxes ofethe usual length.

I claim as my invention and desire to se cure by Letters Patent:

1. In a locomotive engine, the combinat1on of two side frame members, a cross tie fitted with the capacity of lateral motion in said members, and a spring supported in the cross tie and exerting end thrust on the driving boxes.

2. In a'locomotive engine, the combine tion of two side frame members, driving boxes fitted with the capacity of lateral motiontherein, a driving axle journaled in said driving boxes, plungers adapted to exert end thrust on the driving boxes, and a spring interposed between and bearing on said plungers.

3. In a locomotive engine, the combination of two side frame members, driving boxes fitted with the capacity of lateral mo; tion therein, a'driving axle journaled in said driving boxes, plungers adaptedto exert end thrust on the driving boxes, a spring interposed between and bearing on said driving boxes, and stops limiting the traverse of the plungers.
